I'm guessing you are referring to some sort of processor? How many registers? Other yada-yada...

Admin pro tempore on 0gb.us:30000. Ask me if you have a problem, or just want help.This is a signature virus. Add me to your signature so that I can multiply.Now working on my own clone, Mosstest.I guess I'm back for some time.

I built a 7-segment display where there is a button for each number (0-9) and when you press one of them, that number appears on the screen. It doesn't use any microcontrollers or luacontrollers, all it uses are insulated mesecons (plus the corners and T connections), light blocks, switches, mese blocks, and diodes.

It uses a 16-bit architechture, with 256 ROM registers and 32 RAM registers.

Oh, and don't expect it to really work unless you change delayers and button delay to something 100 times the normal one, and setting unused_block_timeout to something far larger (or use the force_load pull).

The program in the computer should make the sum of the integers form 1 to 10, but I never saw it execute a single instruction.

Nore: that would be awesome! If you do go about doing so (it seems like a lot of work), I will certainly add them to the site.

By the way, what are its capabilities? What architecture is it using? From the map it seems like some sort of modified Harvard architecture. In any case flying through it feels like the towers scene from "The Matrix".

12Me21: I'm also looking for a "Back to the Basics" category, where we use only the core features such as wiring and diodes. That sounds like a perfect entry to have.

i made a 4 bit decoder to 7 segment display with luacontrollers

cool!

The node detector is an important part of the mesecons 3D Scanner, the mesecons punch tape computer, and a lot of other more advanced machines. Check out the article at the Mesecons Laboratory for a detailed guide on how to design, build, and improve on it!

Excellent! I tried to build a multiplier myself back when the only logic device was the plug/socket/inverter, but each adder being at least 4x5x4 made the whole thing prohibitively large - the main problem was making a compact XOR gate.

Basic Mesecons is great for people looking to learn about the low-level digital stuff and the logic behind how things work. I like the way the article explains the reasoning behind most of the components built.

You might also want to make sure your Luacontrollers are facing the correct direction. Generally, you can tell which direction I'm building it from the pictures.

In the digital clock article, port A should be facing the lightstone, and port C should be facing the back. If you built it another way, don't fret! Simply replace things like port.a in the code with the correct port, and continue building.

Alternatively, use WorldEdit's //rotate command to rotate your entire structure to the desired orientation. I also added the //orient command a while back, so if you used facedir nodes in your build you can use this to rotate individual nodes like furnaces and delayers.

I'll add notes to all existing and future articles to clarify this point.

Edit: done!

If you look carefully in the image, I used uninsulated mesecon in the second-to-bottom and second-to-top row rather than insulated corner wires. This differs in that the rows above and below it also light up when this one does.

Some people may not know this, but mese blocks themselves transmit signals (though using mesecon wires is much more resource efficient.) I am glad that there is a site that gives tutorials on how to build various things. One day, there might be mesecon machines that are truly fun to play with (like games and such.)
